Just after Cistern, I get into the Sewer, where the monster appears really often ! I finally escape him, I open 2 doors 'nd climb up a ladder for like 15 seconds. When I finally reach out the end of that ladder, I get the loading for the next area ... And , I assume that when it's over, I suddendly go back to my desktop : Amnesia just crashed.

I'm using a MacIntel with snow leopard and I don't have parallel Windows.

I thought it'd be like my " profile " had problems, so I've began a new game again, made it to the Sewer , and it crashes again !
